ANDREW J. HEAVNER AND RICHARD THORNTON, PITTSFIELD, ILL.

WHEEL-CULTIVATOR.

SPECIFICATION forming part. of Letters Patent No. 337,400, dated March 9, 1886.

Application filed July 20, 1885. Serial No. 172,099. (No model.)

To all whom it may concern:

Be it known that we, ANDREW J. HEAVNER and RICHARD THORNTON, citizens of the United States of America, residing at Pittsfield, in the county of Pike, in the State of Illinois,have invented a new and useful Cultivator, ofwhich the following is a specification.

Our invention relates to improvements in cult-ivators of that class specially known as wheel-cultivators, and the object is to simplify and improveexisting implementsof that character.

\Ve attain the purpose of our improvements by means of the mechanism illustrated in the accompanying drawings, forming a part of this specification, and in which Figure 1 is a perspective view of ourimproved implement. Fig. 2 is a central longitudinal sectional view. Fig. 3 is a plan View thereof. Fig. 4 is a detail view of the sleeve and shifting devices. Fig. 5 is a detail view of the plow-standard and mode of attaching it, and Fig. 6 is a central sectional view taken through the line 00 a: of Fig. 5.

Similar parts are identified by similar letters of referencein the different views.

The letter A designates the wheels supporting the axle B, the latter being formed with a bail, 12, carrying the carriage or frame 0. This frame 0 is comprised of substantial side bars, 0, connected by end bars, 0, and intermediate cross-bar, 0

The letter D designates the seat, the stem or foot (1 thereof being secured to the board d, resting on the cross-bars d secured to the rear cross-bar, c, and bar (P, the latter being secured to the side bars of the frame. About the standard of the seat, or about a standard projected from and secured to the board sustaining the seat, is secureda spring, tit-which may consist of a spring-rod wrapped about such standard, with its arms (2' extending forward from the seat, and arranged to have a spreading force, in order that when the free ends of the spring are set against the inner edges of the levers connected to the forward shovels the spring shall operate to press apart the levers when drawn together by the pressure from an opposite direction.

The letter E designates levers having their forward ends pivotally attached to the crossbar 0 of the frame, and their free ends extending back over the axle, and arranged with their inner edges resting against the arms of the spring secured to the foot or standard of the seat, substantially as shown in Fig. 3 of the drawings. These levers have formed in them slots 6, longitudinally arranged therein, and adapted to receive the projected or extended end of the standards of the forward shovels, so that the direction of the, shovels may be guided by operation of the levers at the willof the driver.

The letter F designates the tongue, pivoted or otherwise suitably secured to the crossbar c at f, and also secured against side displace ment by a strap fitted to the tongue and secured to the front cross-bar of the frame, as seen at f.

The letter G represents the plowbeams. These are provided with vertical standards 9, secured to the rear ends thereof, the upper end of which standards is passed through an adjustable sleeve, 9, secured to the end crossbar of the frame, as hereinafter stated. These sleeves g are formed or provided with a bolt, projected from their rear wall, and terminating in a head, 9 formed with a hole, 9*, intended as a bearing for the lever-bar, which is projected through these holes of the bolt heads, as hereinafter stated. The neck of these bolts g is screw-threaded, and a threaded nut, 9 fitted thereto, whereby the sleeve may be secured in position as may be desired. Secured to the side ofthe sleeve is a small sheave or sprocket-wheel, 9. Through the holes in the heads of the bolts of the sleeves is fitted a lever-bar, 9 having a lever-handle, g secured to one end, and arranged to be conveniently accessible to the driver; and at each end of the lever-bar g is fitted a grooved or sprocket sector, 9, to the inner or upper end of which is fastened a line or chain which passes down over the sector; thence over the sheave or sprocket at the side of the sleeve, and,jextending down, has its lower end secured to the plow beam, substantially as shown in the drawings. The rear cross-piece of the frame is formed with longitudinal slots 9, extended through the cross-piece from rear to front, and in these slots the sleeves are secured by means of their bolts and nuts, the purpose being to permit the sleeves to play for the length of the slots; or they may be set therein at any position desired by simply clamping them in position. By the same means the beams of the plow can be arranged at the required distance apart. By means of this mechanism the rear ends of the plow-beam can be raised and the plow lifted from the ground, or their depth regulated thereby. Simply moving the lever in the right direc tion effects the purpose.

Theletter H designates brackets secured to the front cross-piece of the frame, and comprised of the depending bars h, which are perforated, substantially as shown, to receive the shaft or pintle of a sheave, h, and connected at their lower ends by means of a crossbar, It. Attached to a suitable point in the side bar of the frame are braces 7t, extending from their point of attachment to the frame to the lower part of the outside bar of the bracket, the object being to strengthen the devices or brackets. To the forward end of each beam is secured a sleeve, h, which is passed over the crossbar of the bracket, and, being provided with a set-screw, may be set in any desired position on the cross-bar, thus affording a lateral adjustment to the beam to suit different widths of growth.

The letter I designates the front shovels or plows, the lower part or shovel, t', being made of any of the approved forms, and having attached thereto a standard composed of two sections-a lower one, t", and an upper one, i -arranged with their side faces in contact, and fastened together by means of an iron pin or bolt, t", passed through the spliced parts above the bracket, substantially as seen. The standard in immediate connection with the plow is slotted, as at 'i, and has fitted in said slot a flat bolt, i formed with a side projecting lug or finger, 73, adapted to set with its rear face against the face of the upper splice of the standard and serve asa bracepiece. This flat bolt is provided with a hole through each end. Through the rear hole, i, is projected a wooden pin, i which rests against the face of both sections of the standard and serves as a breakpin in cases wherein the strain upon the stand ard is more than it should withstand, the pin giving away under such exigencies, and thus saving the integrity of the standards and the plow. To the front end of the bolt is fastened the brace chain in, having its other end linked to the end of the bracket or rod t secured to the beam of the plow, the object be ing to secure the parts togetherstrong enough to withstand any ordinary strain, and yet so that they shall, in case of accident or undue strain,be torn asunder without material damage to either section. The upper section of the standard of the forward plow is projected through the slots 6 of the levers E, in order that the course of the shovel may be guided and cont-rolled by the operation of the lever.

The letter J designates brackets adapted to hold the standards of the plow or shovel. These brackets consist of a substantial metal bar formed with a cross-head, j, perforated to receive a bolt, and the arms or side pieces, j, provided with perforations in their free end j. A bolt, jflis passed through the perforation of the cross-head and through the beam, and secured by means of a nut on its projecting end. This connection, it will be seen, permits the bracket to be turned and set so as to receive the standards of the shovel at any desired in clination. A bolt, j, is projected through the end perforation of the bracket and through the standard of the shovel,aud secured by any suitablemeans. Thislatter connection, it will be seen, permits the standard of the plow to be swung in either direction about the bolt, holding itin the bracket, and the result of the connections is, that the plow can be turned to,

any position of incline on the axial bolt of the bracket, and at the same time may be moved sidewise by turning on the axial bolt of the standards.

The letter K represents the hind shovels, having their standards secured in the brackets J identical with the forward shovels, eX- cept that the standards of these rear shovels are not extended above the brackets, except sufficiently to give secure fastenings. A brace, It, extends from the standard of the shovel to the beam, and the incline of the shovel is set by means of perforations in the brace in its free end, and securing it to a pin on the beam, substantially seen in the drawings.

The letter L designates the double-tree, pi votally secured to the center of the bail of the axle, as at l. Toeach end of the double-tree is attached a rod, Z, which extends therefrom to the forward part of the carriage, being passed through the sheaves of the brackets, and has connected therewith the singlctree Z".

The operation is readily gleaned from the foregoing description of the parts and their functions, but may be here stated as follows: The draft may be regulated by means of shifting the sheaves on the brackets at the front of the beam to a hi gher or lower position,whereby the line of draft is set accordingly. The depth of the shovels is regulated bytnieans of the lever at the hind end of the frame and beam, and the beams may be set to any width by lateral movement 011 the front rods of the brackets,and by movement of the sleeves in the slots at the rear piece of thefran'ie. The frontshovcls are arranged to operate independently of the back shovels in this, that they may be lined by means of the levers extending within reach of the operator.

The general construction of the implement or machine admits it to be made i n a compact form, whereby the draft maybe lightened, and the weight brought more directly upon the axle. Access to the lever is con venient, and the driver has free and full view of the forward shovels, and, by means of the lever hinged to the frame and controlling the projected standards of the front shovels, may guide them as desired.

What we claim as our invention, and desire to secure by Letters Patent, is-
